Hi all, I have a flock of five chickens, 2 ferals at 5mo and 3 RIRs at 4mo. All of them were raised from chick-time. Of the two ferals, one is a pullet and the other is a roo. In the past two weeks I've noticed that the feral roo picks on the feral pullet -- he jabs at her neck/wingside with his beak, he chases her randomly throughout the day, and he plucks out her feathers. She still HAS feathers, and at first I thought the bunches of feathers on the run ground were from falling out, but then I caught him red-beaked tearing them out. I put him in a small coop/run designed for the RIRs when they were younger inside the main run in the hopes that jail time would fix his attitude. After a week, I let him out, and in a few hours he was back to picking on the pullet. He was also running the three RIRs around, but I expected as much since pecking order. They run into the small coop when he intimidates them, or the feral pullet intimidates them since she doesn't like them either, but my main concern is the feral pullet being picked on since she sticks to the roo like glue despite his terrible behavior! My question is: is this a part of the roo maturing, or is he just a bully? Is there any way to try and 'steer' him on the correct path or should I get ready for my first butchering? The coop is 5x4 and the run is approx. 20x12. Any advice and/or comments are greatly appreciated! Thank you!
